Although two weeks have passed since local elections in Turkey, it's hard to predict when the final results will be announced over who will run Istanbul, Turkey's largest metropole with 16 million residents.
Turkey's Supreme Electoral Council (YSK) will continue to examine appeals from the governing Justice and Development Party on election irregularities after awarding the certificate of mayorship to Imamoglu, the Republican People's Party candidate.
A Turkish opposition party on Wednesday appealed to Turkey's election authority to cancel last month's local poll results in the metropolis of Istanbul. "We will start to serve immediately".
AK Party appealed to the YSK to redo the vote in Istanbul after the recount and asked the electoral body to postpone the handover to Imamoglu.
Imamoglu's margin of victory - the final count put him some 13,000 votes, or less than 0.2 percentage points, ahead of the AK Party candidate and former prime minister Binali Yildirim - prompted several AKP challenges.
But Yildirim struck a conciliatory note on Wednesday evening while stressing that the AKP had not abandoned its appeal.
The party said on Twitter that Imamoglu was due to take office at 6pm.
The repeated challenges by the AKP and MHP have fueled frustration among opposition supporters which spilled over into football stadiums at the weekend when fans chanted at top Istanbul derby matches for the mayoral mandate to be given to their candidate.
CHP Deputy Chairman Muharrem Erkek responded that there were "no concrete documents, information or evidence in the AKP appeal for an annulment".
Wolfango Piccoli, co-president of Teneo political risk advisers, said it was puzzling to call only for a re-run of the mayoral elections, and added that some of the areas where the AKP claimed fraud took place were under its responsibility.
Uncertainty over the election results has also put pressure on financial markets, pushing the lira down almost 5%.
Erdogan had vowed that Turkey would enter a four and half year period with no elections after March 31, during which the ailing economy would be the focus.
If the YSK comes to a conclusion that the Istanbul polls were rigged, then an announcement for the renewal of the polls on June 2 is expected.
